Over the past year, Chris Pratt has joined the likes of Jennifer Lawrence and Mila Kunis as the Hollywood star that everyone wants to be BFFs with. And if you haven't been convinced of his charms yet, perhaps these photos of him visiting sick children will change your mind.

According to Buzzfeed, Pratt recently visited the Children's Hospital of L.A. as Star-Lord, his character in the new Marvel blockbuster 'Guardians of the Galaxy.' The official Twitter feed for the Children's Hospital tweeted the following photo of Pratt putting a smile on a young fan's face.

Chris Pratt Center, an Instagram fan feed dedicated to Pratt, shared the following photos of Pratt posing with various kids.

Pratt was also photographed visiting Dylan Prunty, who has been nicknamed the "Lego Kid" for his amazing Lego creations that he has worked on as a way to forget about his health problems. Prunty suffers from mitochondrial disorder and has spent more time in the hospital than his home over the past two years.

“It distracts the pain. It’s like the best pain medicine,” Dylan's mother told CBS Los Angeles in regards to Dylan's love for Legos.

Pratt starred as the lead character in Warner Bros.' 'The Lego Movie,' which opened to critical acclaim earlier this year.
